Abstract
Implementations provide a receiver circuit that includes: an alternate current (AC)-coupling network to filter an input signal, the AC-coupling network including a first RC filter connected between a first input node and a first common node and a second RC filter connected between a second input node and the first common node; a differential amplifier coupled to the AC-coupling network and configured to receive a filtered input signal from the AC-coupling network and generate an output signal, the differential amplifier including a differential pair of transistors and a common-mode measurement network coupled to source terminals of a first and a second transistors in the differential pair; and a first operational amplifier having an input coupled to output terminal of the common-mode measurement network and an output coupled to the first common node.
